DEVICE FOR STRAIGHTENING CAN-JAR COVERS.

SPECIFICATION forming part of Letters Patent No. 665,517, dated January8, 1901.

Application filed January 31, 1900. Serial No. 3,450. (No model.) i

To all whom it may concern:

Be it known that LANDREW GEEOK, a citizen of the United States, residingat Owosso, county of Shiawassee, State of Michigan, have invented acertain new and useful Improvement in Devices for Straightening Can-JarCovers; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being badto the accompanying drawings, which form a part of this specification.

My invention has for its object an implement for straightening the edgesof j ar-covers after the cover has been screwed down in contact with therubber gasket usually employed.

In the drawings, Figure l is a perspective view of the device. Fig. 2 isan elevation of a portion of a canning-jar, showing the implement inposition in cross-section.

Referring to the letters of reference on the drawings, A represents anannular ring or band of metal, wood, or other suitable material,provided with lugs a, depending from its lower edge, and provided on theinside with an offset portion a, fashioned so as to conform to thecontour of the lower edge of the cover B. On the annular ring A areprovided raised portions A A to afford means whereby the ring may berotated around the cover without the possibility of its slipping in thehand.

0 is the rubber gasket usually employed.

D is the canning-jar.

As is well known, it is a common practice when the covers ofcanning-jars stick to the gasket, and thus prevent removal, to insert aknife or other suitable implement between the edge of the cover and therubber gasket and in some cases to pry the gasket out in order to freethe cover, so that it can be removed.

The employmentof such an instrument causes the edge of the cover to beturned up or to become very irregular, so that when it is desired toagain use the cover it cannot be brought down to form a perfect seal.

The object of my invention is to straighten the lower edge of the coverand to bring the same in close contact with the gasket when screwed intoposition. This is accomplished by placing the annular ring over thecover, when by rotating the same the lugs a a will force the edge of thecover in close contact with the rubber gasket 0, smoothing out allirregularities in the edge of said cover, and thus securing a perfectseal.

What I claim is 1. A device for straightening the edges of j ar-coversconsisting of an annular manuallyrotatable ring adapted to encircle thecover and provided with depending lugs, theirlower edges adapted to bearagainst the edge of the cover and when said ring is rotated, tostraighten out any irregularity in the edge of the cover and force thesame in close contact with the jar or gasket, substantially asdescribed.

2. In a device for straightening the edges of jar-covers, thecombination of an annular manually-rotatable ring adapted to encirclethe cover when in position upon the jar and provided with depending armsor lugs, their lower edges adapted to force the edge of the cover inclose contact with the jar or its gasket, and suitable offset portionson said ring to facilitate rotation, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.

ANDREW GEEGK.
